Change of Salivary Testosterone of Racers after Training Sessions of Different Loading Volume

Salivary testosterone of sprinters and long distance runners be fore and after training sessions and during the recovery period was measured. The study found that salivary testosterone of sprinters significantly decreased after large and medium training loads, and returned to original level after l2 hours. Salivary tesosterone of long distance runners increased after small loading volume, but significant1y decreased after 1arge and medium loading vo1ume, and returned to original level after 6 hours.Change of salivary testosterone of men in a day showed certain regularity, being high in the morning and low in the afternoon. The change of salivary testosterone observed in this study was caused by exercise.

唾液中睾酮的IEMA法测定

本研究建立了唾液睾酮（ＳＴ）的ＩＥＭＡ（磁性微粒分离的酶联免疫）测定法。结果：平均回收率为９２．３５％，重复试验平均变异系数＜５％，血清睾酮（Ｔ）与唾液Ｔ相关系数为：男ｒ＝０．８５２，Ｐ＜０．００１，女ｒ＝０．９０２，Ｐ＜０．００１，与其它测定唾液Ｔ方法的结果相符。本研究提示唾液Ｔ浓度可反映血浆游离Ｔ水平，在临床和体育研究中有实际应用价值。

径赛运动员不同训练量课后唾液睾酮的变化及恢复

测定了短跑、长跑运动员不同训练课前后及恢复期唾液睾酮，发现短跑运动员不同运动量训练后唾液睾酮降低，中、大运动量训练后唾液睾酮显著下降，且恢复需12h以上；长跑运动员不同运动量训练后唾液睾酮变化与运动量有关，小运动量训练后唾液睾酮上升，中、大运动量训练后显著下降，恢复时间要6h以上。对1日内男子唾液睾酮的测定发现唾液睾酮变化具有一定规律，早晨最高，下午最低。本实验运动后唾液睾酮变化非睾酮自身波动，而是运动的影响。
